UNITED STATES PATENTS 601,495 3/1898 Cornell 242 56 A 2 Claims, 4Drawing Figures APPARATUS FORTAKING UP A WEB BACKGROUND OF THEINVENTION 1. Field of the Invention This invention relates toanapparatus for taking up aweb, andmore particularly toan apparatus fortaking up a web adapted for readily replacing the wound web cores.

2. Description of the Prior Art An apparatus for taking up a web afterthe web such as paper, plastic, metal, etc., is treated, is used invarious technical fields, but in any field, this type of apparatus fortaking up a web lowers itse'fficiency in .the whole by the operation forreplacing the core, that is, the operation of removing the core woundwith theweb and of mounting'new vacant core.

SUMMARY OF THE INVENTION It is, therefore, an object of this'inventionto provide an apparatus for .takingup a web which readily replaces thecore so as to improve the efficiency of the .taking up step.

According to one aspect of .thisinvention,.:there is provided anapparatus for takingup a web which comprises one rotary shaft formounting the cores of the wound web-which are rotatablyprovided on. a"plurality of shafts which extendedrradially in .thevertical'plane withthe rotary shaft, and.a device'fordrivingithe shaft for mountingthecores so.as to selectively rotate or stop it at equidistantcircumferential:positions.

The other objects, features and .advantagesrofthis invention will becomeapparent .from the following. de-

- scription taken in conjunction with thetaccompanying drawings.

FIG. 4 is a plan view ofaportion of .thezapparatus.

DESCRIPTION OF TI-IE 'PREFERRED EMBODIMENT Reference is now madetothedrawings, which show one embodiment of the apparatusaccording tothisinvention.

The apparatus fortakin'gup a web ofthis'invention comprises a take-up.unit i 2 rotatable about one "main shaft 1, in which unit L2, fourshafts21, 22,123 andk24, for mounting the coresextend radially in the verticalplane with the main shaft 1. This take-up..unit.2 may rotateintermittently 90 degrees around .theaxis of the main shaft 1 so thatthe respective shaftsi21 to..24..are brought, in turn, to equidistantcircumferential .positions, particularly in sequence to a verticalupstanding position. lnthe apparatus of .this embodiment, thisintermittent rotation is conducted bya thick wheel'3 of a genevagear anda follower '4, but may'also bedone by anothertmeans such asonecyclemotor.

In FIGS. 2 and 3, the structural detail of the-take-up unit 2 and itsdriving system .areshownAArdrive shaft 6 havinga take-up shafttransmission gear 60 is. supported by aframeS provided at the side of:theapparatus,.and the shaft:6.is.drivenbyengaging a'belt on the pulley:61 fixed tothe drive shaft. 6. A turret :plate 7 is fixed to the mainshaft 1, and four take-up transmission shafts 81, 82, 83 and 84 aresupported in parallel by the turret plate 7.'To the take-up transmissionshafts 81 to 84 are fixed take-up shaft rotary gears 91 to 94 engagingthe take-up shaft transmission gear 60 and interlocking gears 11 to 14.The interlocking gears 11 to 14 are disposed in the take-up unit 2 andalways in engagement with the take-up gears 25, 26,27 and 28 of the endof the take-up shafts 210, 220, 230 and 240 fixed to the shafts 21 to 24for mounting the core of the takeup unit 2. The take-up unit 2 has keeprollers 31, 32,

' 33and 34 for winding the web onto the core mounted to the shafts 21 to24 without looseness. Bearings 41 to 44 rotatably support the take-upshaft 210.

In the take-up unit 2 thus constructed, if the take-up shaft rotary gear91 is engaged with the take-up shaft transmission gear 60, when thedrive shaft 6 is rotated,

the take-up transmission shaft 81 is rotated through the transmissiongear 60 and take-up shaft rotary gear 91,

and the takesup shaft gear 25 is rotated by the interlock gear 1 1 sothat the shaft 21 for mounting the core fixed to the take-up shaft 210is rotated.

Whereupon, the other shafts 22, 23, 24 for mounting the core arestopped. Then, if the core is at first .mounted onto the shaft 21 formounting the core in the .above state so that the web is taken upthereon and when the taking-up is completed the web is cut out at thesame time the main shaft 1 is rotated at an angle of .inthe direction asshown byan arrow in FIG. 1 by the;.geneva gears 3 and 4, with the resultthat the takeup shaft rotarygear 94 is engaged with the take-up :shafttransmission gear 60 so that the rotation of the .drive shaft-.6 istransmitted to the shaft 24 for mounting the.core,:shaft24 moving tovertical upright position.

Here, in FIG. 1, the web brought to the right side together withthecore, which is removed, where vacant core is installed. Whereupon, theshaft 24 already starts to take up the web sothatthe taking-up iscontinuously conducted.

Therefore, it is not necessary that a special step and time forreplacing the web roll after completion of taking up occurs, so that thetime of the taking-up step is greatly shortened.

The replacement of the core is conducted only if the core is pulled inthe direction of the take-up shaft, and vacant core is not installedwith sliding axially and accordingly the operation is very simple.

ltshould beunderstood fromzthe foregoing description that since thetake-up shafts are radially provided -with respect to the main shaft ofthe turret so that this .is rotated around the main shaft in theapparatus of this invention, the apparatus may be simply constructed so.as to greatly improve the effiency of the steps of the operationthereof.

What is claimed is:

1. Apparatus for takingup a web comprising:

.a horizontally disposed rotary shaft,

a pluralityof rotatable core mounting shafts extending radially in thevertical plane from said rotary shaft and rotatable as an arraytherewith about the axis of said rotary shaft,

means for indexing said rotary shaft to dispose each core mounting shaftof said array at sequential equidistant circumferential positions and todispose a selected shaft in vertical upright position, va drivingmechanism, and

said indexing means further including means for opgear wheel andfollower are provided to rotate the rotary shaft about its axis from oneindex position to another.
